90 from GPU and maybe a 45 or 90 from the CPU.
I always try to use as few as possible 45 and 90 fittings, but specially whit clear soft tubing (ZMT is less flexible), what seems like a sharp but ok curve, once the coolant warms up a bit is enough to make the tubing slightly more flexible and it happens.
Anti link coils would help, but visually would send you back 10+ years ago, when I first start watercooling...
